Technical specification 6.8.1 requires tha … Technical specification 6.8.1 requires that written procedures shall be established, implemented and maintained as recommended by Regulatory Guide 1.33, Revision 2. Specifically, procedure MA-AA-716-21 0, Performance Centered Maintenance (PCM) Process, Rev. 10, establishes guidance that the licensee identifies and implements new PM tasks within 18 months. Contrary to the above, the licensee failed to identify and implement a PM task to clean and inspect the Emergency Diesel Generator\'s (EDG) fuel oil drain lines in 2007 in accordance with their procedure. Consequently, the \'A\' EDG (EG-Y-1A) fuel oil drain lines clogged and caused excessive fuel oil leakage from the fuel oil injector pumps. Operators identified this degraded condition during PMT folloWing unrelated maintenance on EG-Y-1A. The fuel oil leak resulted in operators declaring EG-Y-1A inoperable on April 30 and May 1, 2010. This finding was more than minor because it was associated with the equipment performance attribute of the mitigating systems cornerstone and affected the availability of EG-Y-1A to respond to an initiating event to prevent undesirable consequences. The licensee entered the condition into their corrective action program (IR 1064102) and took immediate corrective actions to address affected clogged drain lines on EG-Y-1A. In addition, the licensee initiated corrective actions to perform the PM task during the next scheduled maintenance outage for all onsite EDGs and to implement the PM task on the recommended frequency. the PM task on the recommended frequency. +
